9mm diameter, 4mm height aircraft-shaped electromagnetic SMD buzzer

What is an SMD Buzzer?

An SMD buzzer is an electronic device that can produce a buzzing sound. It is commonly used as a replacement for traditional electric bells or as an audio signal generator. The term "SMD" stands for Surface Mount Device, which refers to the method of mounting electronic components directly onto the surface of a printed circuit board (PCB). This integration allows for a compact and space-saving design.

Features of the Aircraft-shaped Electromagnetic SMD Buzzer:

The aircraft-shaped electromagnetic SMD buzzer has several notable features that make it a popular choice in various industries. Firstly, its small size, with a diameter of 9mm and a height of 4mm, allows for easy integration into compact electronic devices. This makes it suitable for applications where space is limited.

Additionally, the electromagnetic design of the SMD buzzer enables it to produce a loud and clear sound. It operates by utilizing an electromagnetic coil that generates vibrations when an electrical current is passed through it. These vibrations are then converted into audible sound waves, resulting in a distinct buzzing sound.

Applications of the Aircraft-shaped Electromagnetic SMD Buzzer:

The aircraft-shaped electromagnetic SMD buzzer finds wide-ranging applications in various industries. In the household appliance sector, it is commonly used in devices such as washing machines, refrigerators, and microwave ovens to provide audio notifications or alarms. Its compact size allows for seamless integration without compromising the overall design of the appliance.

In the banking industry, the SMD buzzer is utilized in ATMs and cash deposit machines to provide audio feedback to users. This ensures that users are alerted to the completion of a transaction or any issues that may arise during the process.

Furthermore, the SMD buzzer is widely employed in the computer, printer, and copier industries. It is used to indicate error messages, signal the completion of a task, or provide audio feedback during the printing or copying process.

In the automotive sector, the SMD buzzer is integrated into various electronic devices such as car alarms, parking sensors, and navigation systems. Its compact size and loud sound output make it an ideal choice for these applications, ensuring that drivers are alerted to potential risks or changes in their surroundings.


The aircraft-shaped electromagnetic SMD buzzer is a versatile electronic device that finds applications in a wide range of industries. Its small size, loud sound output, and ease of integration make it a popular choice for various electronic devices, including household appliances, banking equipment, computers, printers, automotive electronics, and more. As technology continues to advance, the demand for compact and efficient audio signal generators like the SMD buzzer is expected to grow.
